Vented certain new and useful Improvements Secured to the frame A and extending in in Rotary or Disk Harrows; and we do dethe line of draft is the bar D,-the ends of clare the following to be a full, clear, and which are bent to form the flanges (l, which exactdescription of the invention, such as are secured to the upper face of the frame, oo

The rear end ties of construction and in the combinations, of the tongue is formed with a shoulder e,

Fig.3 is a plan View of the tongue and F F are frames formed, preferably, of flat drivers seat removed. metal and made rectangular in shape, with Like letters of reference indicate like parts the ends bentdown'ward upon a lower plane throughout the several views. than the sides, and upon the under faces of 3 5 -Reference now being had to the details of these ends are secured boxes or bearings f, the drawings by letter, A designates the frame, in which are journaled the shafts G, carrying formed of metal in substantially the shape a plurality of disks orrollers G, of ordinary shownthat is, rectangular or elongated, and construction. These bearings or boxes may preferably with rounded ends. On each. side be of any known construction; but I prefer 0 1,0 of the frame, on the upper face thereof, I sea chambered box to receive a ball on the end cure the L-shaped bar a, and to the under of the shaft and waste or packing in said side I secure the flange b of the uprights B, chamber. which upon their outer faces are formed with The side bars of the frames F are provided the vertical recess or groove 1), with the guidewith lugs or brackets g, through holesin which 5 flanges 17 formed integral therewith. pass the shafts H, one end of each of which is O O are wheels journaled upon the stubbent upon itself, as shown at h, to embrace the axles O and secured thereon against endwise side bar of the frame A, and is formed or prodisplacement by means of the nuts 0 each, vided with an upward1y eXtending bracket h, of said stub-axles having secured thereto a the other end of the shaft passing through a I00 50 vertical bar or plate a, which works in the lug 71 depending from the guide h and pro groove or recess Z) in the upright and guided vided withanut h. These lugs gin the movement of the frames by mechanism hereinafter described are guided by the curves f of the frame A.

The frames F rock on their bearings independent of each other, and are thus free to adjust themselves to any inequalities in the ground.

On each shaft H is placed a sleeve '5, and t" is a nut screwed on said shaft and adapted to bear against said sleeve and bind it against the lug g to allow the said frames F to rock less easily when occasion may require.

J ournaled in the vertical portion. (1 of the bar I) is the shaft 1, the forward end of which is provided with the lever J, the ends of which are connected by means of the rods or bars J with the brackets h. To the other end of the bar D is secured the lever K by means of an adjusting-nut], and said lever upon opposite sides of its fulcrum is pivotally connected with the lugs 7L2. The lever K is provided with a suitable locking-catch to engage the rack-bar E and hold said lever and the frames F in their adjusted position. The movement of the lever changes the inclination of the frames F in relation to the line of draft.

M is a footlever pivoted to the tongue, and its hooked end is connected by means of a cord or chain M with the inner end of the diskframe F, there being two fo0t-leverson e up on each side of the tongue, one for each diskframe-said foot-levers being for the purpose of raising the inner ends of the disk-frames, as will be readily understood.

The device is simple, easily adjusted, and will be found to be very efficient in operation.

\Yhat we claim to be new, and desire to secureby Letters Patent, is-

1. The combination, with the frame A, of the longitudinal shafts supported at their ends on the frame A,the frames F, free to oscillate on said shafts, and the disks carried by a shaft arranged transversely of the frames F, substantially as and for the purpose specified.

2. The combination, with the frame A and the two independent harrow-frames free to es cillate independently of each other on longitudinal shafts, of the transverse shafts journaled in said frames and carrying the disks, the shaft I, and connections between said shaft and the longitudinal shafts of the harrowframes, substantially as shown and described, and for the purpose specified.

3. The combination, with the frame A, formed with the curves f, of the harrow-frames provided with the lugs g, and the means for adjusting said frames, substantially as and for the purpose specified.

4. The combination, with the frame A and the tongue, of the independentrocking harrow-frames, the pivoted foot-leve1's, and the chains connecting said levers with the inner ends of the barrow-frames, substantially as and for the purpose specified.

5. The combination, with the frame A and the two independent harrow-framcs, of the shafts of said harrow-frames, the shaft 1, the operating-lever on one end of said shaft l, and the rods connecting the shafts of the harrowframes with the said lever and shaft- I, substantially as and for the purpose specilied.

In testimony whereof we atlix our signatures in presence of two witnesses.
